T0 aZZ whom it may concern Be it known that I, EMORY J.L1rrs,aciti zen of the United States, residing in the borough of Fountain I-Iill, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Ieeling Skeins, of which the 'following is a specification.

In machines for winding skeins, of the class in which the traverse of the thread or yarn guiding raill is eiiected by a crank whose wrist-pin engages a slot or other path or way on the rail or a suitable part attached thereto, the said way extends at right angles to the path of reciprocation of the rail, so that, while the rate of rotation of the reel on which the skeins are wound of course remains constant throughout each cycle of movement of the crank, the rate of reciprocation of the rail varies to such an extent that whereas the rail has considerable movement imparted thereto by the crank while the latter is passing through those arcs of its cycle, each of 90 degrees (approximately), whose chords are substantially parallel to the path of travel of the rail, it obtains relatively little movement while it is passing through either of the remaining arcs of 90 degrees (approximately). In other words, what amounts substantially to a dwell at each of the limits of movement of the rail is excessive in extent in proportion to the amount of movement which the rail obtains while the crank is moving through either of the two arcs of its cycle, each of 90 degrees (approximately), whose chords are parallel to the path of movement of the rail. A serious consequence of this is that the material of the skeins is deposited in greater quantity at the sides of the skeins than at the middle, this being the more pronounced, of course, the greater the yardage of the skeins. Skeins so wound, especially those of oonsiderable yardage, possess various disadvantages well recognized by those familiar with this art, among which it will be sufficient to mention the dificulty of withdrawing the thread or yarn from skeins so consti tuted (the winding being non-symmetrical in character and the convolutions of each layer being of unequal lengths) without entangling the thread or yarn.

The object of this invention is to provide a traverse motion for machines for winding skeins and other wound packages wherethereof.

In the accompanying drawings, wherein the invention will be found fully illustrated, Figure 1 is an end elevation of a skein winding or reeling machine of the class above referred to; Fig. 2 shows skeins wound on a reel by the use of my invention; Fig. 2a shows a skein wound on a reel by the use of the traverse motion commonly employed; and, Figs 3, 4, 5 and 6 are semi-diagrammatic views illustrating my invention.

A conventional machine of the class in which the thread-guide-carrying rail is reciprocated from a rotating crank is shown in Fig. l, a beingthe frame, b a reel journaled therein and furnished with the friction wheel c, al the driving wheel on which the friction wheel bears and by which it, and consequently the reel, is rotated, e the threadguide-carrying or traverse rail sliding longitudinally and horizontally in suitable guides, and 1n the present case provided with or including an arm or bracket f, and g a suitably journaled rotary shaft geared with the reel shaft at one end, as at it, and at the other end provided with a crank whose wrist-pin j is engaged with the contact way, now to be described, which said arm affords. Said way is preferably in the form of a slot whose up er and lower ends la and k are vertical atv right angles to the path of travel of the traverse rails), one of which is offset laterally of the other, and whose intermediate portion 76 is oblique. Now, on reference to Figs. 3 to 6 it will be seen that while the wrist-pin j is passing through either of the arcs, of 90 degrees (approximately), of its cycle whose chord is parallel with the path of travel of the rail e, the wrist-pin being then engaged in one of the portions lo la of the slot, and this being at right angles to the path of travel of the rail, the latter will obtain a lateral movement in one direction or the other equal to the length of the chord of said arc-for example, a point as Z on arm f will travel from position 1 (Figs. 3 and 4) to position 2 (Fig. 4); and that while the wrist-pin is passing through either of the other two arcs, each of 90 degrees (approximately), of its cycle, the

' wrist-'pin being then engaged in the portion 76 of the slot, and this being oblique tothe path of travelof the rail, the latterwill'obtain a short movement YinY one direction (point Z reaching position 3, Fig. 4) and thenvr a long movementin the opposite direc-Y tion (pointfZ reaching position 4, FigQ),

the aggregate of vthese two lattermovements being equal to a very considerable part of that obtained Vfrom the wrist-pin `when traveling in either of the liirst twonamed arcs. Thus, whereas according; to the traverse-motion heretofore employed, the vrail stands practically at a dwell forthe whole extent of movement of the wrist-pin through "the relatively lateral arcs of its cycle, ac-

vbeing formed with side-ridges o, as in Fig.

2a,'they are perfectly uniform in thickness from side toside, as in Fig. 2.Y Y

-The' crank vis indicated by arrows as ro-Vv tating counter-clockwise in Figs. 3 to V6; substantially the same result is accompllshed when the crank rotates'clockwise; Havingthus fully described my invention, what I claim as new anddesire tose' cure by Letters Patent is:-

In combination, a frame, a rotary member onwhich to windthe material, anotherrotary member geared withtheir'st member to rotate in unison therewith `and havingan .eccentric vvrist-pin, and a` thread guiding `member arranged to reciprocatev paralleltoV Ithe axis ofl-rotationofn the first rotary member and vhavingv a' lcontact way enga'ged1 by Y saidr'wrist-pin, said Contact way havin-gits v.en d, Vportions laterally offset relativelyf Yto each other `and each kextending substantially at right angles tothe path of movement of the thread-guiding member'andhaving its intermediate portion oblique tosaid path.

Y In testimony whereofl affix my signature.V
